WASHINGTON (AP) ? Gun control activist Mark Kelly says a proposed national gun background bill under discussion in the Senate should include better access to mental health records that could prevent psychologically disturbed people from obtaining guns.

Kelly, a former astronaut and husband of former U.S. Rep. Gabrielle Giffords, said Sunday that the suspect accused of severely wounding his wife could not have bought the guns he wielded if a background check had exposed his mental problems.

Jared Loughner pleaded guilty to shooting Giffords and killing six people in Tucson in January 2011. Case records released last week showed Loughner passed a background check despite evidence of his agitated mental state.

Kelly pressed for the proposed background check law in an interview on Fox News Sunday.
